We have a 55 gallon tank with a Rena XP2 filter block. From bottom to top we use 2-20, then 2-30, in the next basket activated carbon, then biochemical stars with two microfiltration pads to complete it. Works very well. Change filters every 2-3 months and never had any problems although we tend to overfeed :-( Haven't noticed any real difference to the SUPER filters.
